ABSTRACT:
A long, slender tool for tightening and loosening elongated hex-head nuts (wing knobs) associated with vertical filing clamps. The tool includes an elongated hexagon shaped hole located on one end which cooperatively engages a corresponding shaped elongated hex-head nut (wing knob). A plastic coated handle is use to provide leverage in applying torque to the elongated hex-head nut (wing knob). At the opposite end of the wrench is a common hexagon shaped hole for loosening and tightening a 5/16" hex-head nut. Located closer to the elongated hexagon shaped hole than to the common hexagon shaped hole is a vertical offset.
